The Rolling Spring Roll in Farmingdale and Syosset is just as tasty for takeout as it is for a quick sit-down meal. The Vietnamese eatery started as a food truck. Recommended: all banh mi sandwiches, particularly the classic pork variety; pork spring rolls; vegetarian spring rolls; pho soup with either chicken, beef or vegetables; grilled beef satay; grilled lemongrass chicken. $-$$
